Title: Analogues of phloroglucinols from eucalyptus plant varieties and related compounds and their use in treating neurodegenerative disorders
Inventor: ZHU JOHN JIAO LONG
IPC: A61K31/05
Filed: 2008-11-15
Abstract: Analogues of phloroglucinols that have been extracted from the oils of the Eucalyptus plant, which may be useful in the treatment of neurodegenerative diseases. Various compounds based on the naturally occurring O-prenylated analogue (1), grandinol (2) and jensenone (3) were prepared. In general, the compounds are derivatives of 1,3,5-trihydroxybenzene, including formylated, acylated and alkylated derivatives and alkyl or alkenyl ethers. The compounds may inhibit activation of the platelet activating factor receptor (PAFR) and may be useful in treating neurodegenerative disease, e.g. Alzheimer's disease or dementia, and nerve cell damage due to stroke or ischaemia. Binding of the compounds to a target, e.g. DNA, a receptor or an enzyme, may be detected.

Title: Protection scheme for VCAT/LCAS on SONET/SDH networks with virtual paths switchable between active and standby states
Inventor: HONMA HIROYUKI
IPC: H04J3/00
Filed: 2009-01-22
Abstract: Virtual Concatenation (V CAT) and Link Capacity Adjustment Scheme (LCAS) are used to transport large data streams across SONET (Synchronous Optical NETwork) and SDH (Synchronous Digital Hierarchy) systems. Redundancy is provided by specifying working paths and protection paths within a Virtual Concatenation Group (VCG) whose total bandwidth exceeds that which must be transported. Traffic may be spread across both working and protection paths and any failed path is dropped from the VCG, reducing total bandwidth. In the invention protection paths are kept on standby and only activated when a working path fails, additionally failed paths are not dropped from the VCG.

Abstract: A dielectrically loaded quadrifilar helical antenna, suitable for operation with circularly polarised signals, comprises a solid dielectric core 12 of material with a dielectric constant greater than 5 which has a side surface and two end surfaces and is preferably cylindrical. An antenna element structure 10 provides four pairs 10AA - 10DB of substantially helical conductive paths, where the said paths have different electrical lengths. This structure includes first and second mutually adjacent helical elongate conductive tracks 10CA, 10CB, which may have different average widths and which are separated by an elongate channel or slit 11C which may be formed in a meandering manner. The tracks form an antenna element on the core side surface 12C and the width of the slit 11C is less than half the distance between an antenna element 10CA, 10CB and that of a neighbouring antenna element 10DA, 10DB. Each pair of helical conductive paths may be linked to a feed via linking conductors provided on an end surface 12D of the core 12. The solid dielectric material may be arranged to occupy a major part of the interior volume of the core 12. The antenna may provide a compact arrangement which may operate over a broad bandwidth.

IPC: F01D21/04
Filed: 2009-06-30
Abstract: A fan casing is provided for a turbofan gas turbine engine. The casing has an annular shell 1. The casing further has a leading edge reinforcing rib 6 extending radially from the annular shell. The axial position of the leading edge reinforcing rib is between a first plane i perpendicular to the casing axis and 60 mm forward of the leading edges of the fan blades L, and a second plane ii perpendicular to the casing axis and 20 mm forward of the leading edges of the fan blades. The casing further has a fan track liner 11 mounted to the radially inward side of the annular shell. The liner provides a shroud for the tips of the blades.

IPC: G16Z99/00
Filed: 2009-07-23
Abstract: The present invention provides a computer-implemented system and method that is adapted to listen continuously to data streams from a drilling operation 10, 11 and to process the data using a data analysis server 14 to generate a situation description for a current drilling situation in a form useful for automated continuous matching with a set of past cases stored in a knowledge database 17. The invention implements a case-based reasoning (CBR) approach to match the current drilling situation as defined by the situation description with one or more stored past cases having a degree of similarity above a predetermined threshold level. Matching cases are displayed to the user in the form of a visual display, which may take the form of a polar plot. The user may then retrieve and view the details of a past case and take appropriate action based on drilling advice provided within the past case.

Abstract: 527,304. Stapling. BRITISH UNITED SHOE MACHINERY CO., Ltd., ELLIOTT, H. E., and MAWBEY, L. (United Shoe Machinery Corporation, in part). April 1, 1939, Nos. 10196/39 and 5246/40. [Class 89 (iii)] Relates to machines of the kind described in Specifications 294,640, [Class 89 (iii)], and 401,706, wherein a staple is caused, during driving, to engage a deflecting member whereby it becomes curved within the work, and consists in modifications of the driving and deflecting means to ensure a staple to be driven far enough into the work to cause its head to be slightly embedded therein. The driver may be tilted, for the final small fraction of its movement, or the deflector may be removed to allow the driver to punch the staple home. The driver 13 is actuated by a lever 23 actuating a lever 21 as described in the prior Specifications. The driver guide is pivoted at 19 and the driver shank pivoted at 49 to a lever 51 guided by links 57, 53, of which the latter forms one arm of a bell-crank lever the other arm 33 of which is linked to the lever 21. The links 57, 53 are pivoted to a bracket slidable towards or from the deflector on rotation of a screw 47. In operation the lever 51 travels rearwardly in a substantially straight line till near the end of its driving stroke, when it tilts clock-wise and tilts the driver 13 and its guide toward the upright position. The staple transferrer 11 described in the prior Specifications is divided near its lower end to allow the lower end to descend with the staple driver and maintain its guiding action. In a modification, the deflecting member 75 described in the prior Specifications is carried by a lever 83, urged clockwise by a spring 91 against an adjusting stop 93. A slide 97 with a wedge-shaped end is actuated by the lever 107 to raise the deflector just at the end of the driving stroke. A projection 115 extends from the inside staple former and enters a groove in the deflector 75 to prevent upward movement of the staple.

Abstract: 208,975. White, A. E., (Westinghouse Air Spring Co., Inc.). April 17, 1923. Pneumatic springs. - A pneumatic shock-absorber comprises a tube 3 secured to a casting 5 and provided with a head 4 which encloses a highpressure cushioning- space 8. Threaded on a piston-rod 10 is a member 13 carrying a cupshaped packing-ring 6 pressed thereon by a tube 19 which engages a member 14 secured to the piston-rod 10 by a nut 16, and a cup-shaped packing-ring 7 is held on the member 14 by a follower 24 secured on the piston-rod 10 by a nut 25. The piston-rod 10 is bored axially to form a chamber 28 which is covered by a cap 29. Oil is introduced into the cushion-space 8 and if it leaks past the packing- ring 7 it passes through holes 31 in the tube 19 and passages 30 in the piston-rod 10 to trap a constant mass of air in the chamber 28. Continued leakage of the oil increases the pressure in the chamber 28 until it exceeds the minimum pressure momentarily obtaining in the high-pressure cushioning space 8 when oil is forced back to the upper side of the packing-ring 7. The space 9 below the piston forms a recoil cushion, and a packing-ring 17 arranged oppositely to the packing-ring 6 prevents air from leaking past it from the space 9.
